looks like a leg chopper, it would be amazing to see someone riding such device to its potential, somehow I think safety concerns will not allow it to market wide market, but great to see it developing.

“It works on electricity and can fly at five metres height and carry a policeman during emergency situations and heavy traffic. The bike can also fly without a passenger and and can go up to 6 kilometres. It can fly for 25 minutes and can carry up to 300 kg of weight at a speed of 70km/h,” First Sergeant Ali Ahmad Mohammad from the VIP Security Department in Dubai Police told Gulf News.

Drone Shield looks like a firearm, but it doesn't shoot bullets. Instead, it can send such an intense signal towards a drone that it will simply lose its bearings and float down towards the ground. This solution is much better than, say, a shotgun, because a shotgun can't typically hit a target 2 kilometers away, and if it does make impact, the drone isn't going to fare too well.

designboom is based in milan, beijing and new york and has gained a global reach of 4 million readers and
450,000 newsletter subscribers.

founded in milan in 1999, designboom is the world's first and most popular digital architecture and design magazine. media is still the connective tissue of society, and compared to 1999, the internet has come a long way. during this time, creating a digital publication was still primarily the business of tech-savvy nerds but online publishing has gone from something abstract to being a central element in how many of us live and work. today, when people are searching for something, they’ll look it up online.

drones may spend most of their time up in the sky but as buildings rise and urban areas grow denser it would be handy if they could navigate their way through the streets too. well researchers from the university of zurich and the national centre of competence in research have come up with a control system which could offer this whilst simplifying drone learning altogether. by using a deep learning algorithm they’ve dubbed dronet, the system enables them to autonomously navigate these types of settings, by showing them how cyclists and cars do their thing.

in late december 2017, ANAS launched a 30-million-euro call for proposals, aimed at contractors, to build the new smart road infrastructure according to CRA’s design specifications. the smart highway program will be implemented on more than 2,500 kilometers of roads and highways.

Technological change, increased regulatory requirements and escalating cost pressures are combining to reshape transportation and shipping at a pace not seen in a century. This will lead to new ways of thinking and revolutionary breakthroughs in the industry.

Vehicles that bring goods to homes and businesses in the “last mile” of delivery will be the first to undergo electrification, but the sector itself is ripe for more than just powertrain disruption.

That’s the consensus of UPS, Chanje and Workhorse Group executives speaking at a panel on “the last mile hurdle” at the ACT Expo green vehicle conference in Long Beach, Calif., Wednesday.

There’s more to it than just building and deploying electric vehicles. To Chanje, a Los Angeles-based electric-vehicle manufacturer, the trucks are only a foot in the door.

Includes:

However, Chanje’s last mile vision is broader, he said. “If we think about a zero incremental cost mile, it starts with autonomous driving.”

Autonomous driving removes the driver – one of the largest operational costs – lessens accidents and allows more data integration. Paired with a solar energy production and a reduction in maintenance costs, the incremental mile costs almost nothing, Hausmann said.

“The thousandth mile doesn’t cost you any more than if you were running 500 miles,” he said. “Where we’re going is true last mile ecosystem disruption.”

... and:

But the Loveland, Ohio, company sees the future of last mile in drone technology. Duane Hughes, president and chief operating officer of Workhorse, said it used one of its UPS-owned delivery vans to deploy a package-delivering drone in Tampa, Fla., in February 2017.

“It was the first live parcel delivery via drone in the United States,” Hughes said.

UPS spends $1 per mile in fuel and maintenance costs to deliver a package with a gasoline version of the vehicle in the drone delivery. Using the electric vehicle drops the cost to 40 cents per mile. Using the drone to deliver a package reduces the cost to 3 cents per mile.

So I looked around and sure enough, there is a fair amount of proof of concept flying electric hydrogen aircraft or ("Flying cars").
But Hydrogen drones seems to be something where there is an active commercial market, some people need a lot more flying time/range.
